A nurse provides care to a 6-month-old infant.Which observation should be reported to the pediatrician?
Grasps objects voluntarily.
Posterior fontanel is closed.
Birth weight has doubled.
Demonstrates head lag (lack of head control).
The Correct Answer is D
Choice A rationale
A 6-month-old infant typically grasps objects voluntarily, which is a normal developmental milestone.
Choice B rationale
The posterior fontanel usually closes between 2 to 3 months of age, so it being closed at 6 months is normal.
Choice C rationale
It's expected for an infant's birth weight to double by about 5 to 6 months of age, indicating healthy growth.
Choice D rationale
Head lag in a 6-month-old indicates a delay in motor development and should be reported as it can signal neurological issues.

Explanation
Step 1: lb ÷ (2.2 lb/kg) = 10 kg.
Step 2:.5 mg/kg/day × 10 kg = 15 mg/day.
Step 3: mg/day ÷ 4 doses/day = 3.75 mg/dose.
Step 4:.75 mg ÷ 1 mg/mL = 3.75 mL per dose.
The calculated answer is 3.8 mL (rounded to the nearest tenth).
Correct Answer is C
Explanation
Choice A rationale
A properly fastened harness and securely anchored car seat are essential for infant safety. This statement indicates correct practice and does not require further teaching.

Using an infant model car seat that is securely anchored is appropriate for a 6-month-old infant. This statement is correct and does not indicate a need for further teaching.
